Congresswoman Gabrielle Giffords made her first public appearance on Monday since being shot in the head in January, standing and waving to the crowd at a NASA awards ceremony held at Space Center Houston. She didn't speak publicly, but "appeared to chat with people sitting around her, and laughed" at the introduction of her husband's crew. As encouraging as the appearance might have been, Giffords' staff has been attempting to manage over-optimistic expectations; her doctors have said that it'll be at least a year before they have a sense of the extent of her recovery.
